2. Affected pomp; bombast; swelling words or expressions; false magnificence or sublimity. [R.]

Better, however, to be a flippant, than, by a revolting form of tumor and perplexity, to lead men into habits of intellect such as result from the modern vice of English style. --De Quincey.

Innocent tumor, or Benign tumor, one which does not of itself threaten life, and does not usually tend to recur after extirpation.
